CLI Command Modes
Enter the vlan vlan-id global configuration command to access config-vlan mode:

Switch(config-vlan)#
The supported keywords can vary but are similar to the commands available in VLAN configuration
mode. To display a comprehensive list of commands, enter a question mark (?) at the prompt.
Switch(config-vlan)# ?
For extended-range VLANs, all characteristics except the MTU size must remain at the default setting.
To return to global configuration mode, enter exit; to return to privileged EXEC mode, enter end. All
the commands except shutdown take effect when you exit config-vlan mode.
VLAN Configuration Mode
You can use the VLAN configuration commands to create or modify VLAN parameters for VLAN IDs
1 to 1005.
Enter the vlan database privileged EXEC command to access VLAN configuration mode:
Switch# vlan database
Switch(vlan)#
The supported commands can vary depending on the version of software in use. To display a

To return to privileged EXEC mode, enter the abort VLAN configuration command to abandon the
proposed database. Otherwise, enter exit to implement the proposed new VLAN database and to return
to privileged EXEC mode. When you enter exit or apply, the configuration is saved in the VLAN
database; configuration from VLAN configuration mode cannot be saved in the switch configuration file.
Line Configuration Mode
Line configuration commands modify the operation of a terminal line. Line configuration commands
always follow a line command, which defines a line number. Use these commands to change terminal
parameter settings line-by-line or for a range of lines.
Use the line vty line_number [ending_line_number] command to enter line configuration mode. The
new prompt means line configuration mode. The following example shows how to enter line
configuration mode for virtual terminal line
7:
Switch(config)# line vty 0 7
The supported commands can vary depending on the version of software in use. To display a
comprehensive list of commands, enter a question mark (?) at the prompt.
Switch(config-line)# ?
To exit line configuration mode and to return to global configuration mode, use the exit command. To
exit line configuration mode and to return to privileged EXEC mode, enter the end command, or press
Ctrl-Z.
